Freiberger Probierkunde — Silbererz-Probenahme
The traditional dry assay (Trockenprobe) and cupellation (Kupellation) techniques for determining silver content in ore samples, developed in the Freiberg mining region of Saxony from the 12th century and codified by Georgius Agricola in De Re Metallica (1556) — the foundational text of European mining and metallurgy. The Freiberg assay tradition underpinned one of the most economically significant silver-producing regions in medieval and Renaissance Europe, supplying the silver for the Meissen Silbergroschen that financed the Saxon Electors and eventually funded the founding of the Meissen porcelain Manufaktur (CRAFT-1170). The Probierer reads ore content through the weight and appearance of the resultant silver bead.
